ARFF (Attribute-Relation File Format) is a type of file extension used primarily with Weka data mining and machine learning software. The ARFF format is an ASCII text file that always ends with the extension .arff. It describes a list of data-attributes along with their properties, as well as the data-instances based on these attributes. Each attribute is described by its name, type, and a list of possible values/classes in case of nominal/categorical attributes. This list of attributes and the correlated data-instances gives rise to a dataset.
ARFF Structures and Usage
The ARFF file convention begins with a header line, which provides meta information about the dataset such as the name of the dataset, the name of the relation it describes, and its associated attribute types. This is followed by a series of lines describing each attribute in the relation. These lines contain the attribute’s name, its type, and any range, window or discrete values it may contain. Finally, the dataset instances are described next, listing each data instance in its own line and using commas to separate each value.
It has similarity with other plain text file extensions such .csv, dat, and .txt. ARFF files provides a way to store complex information that could be analyzed in Weka, such as medical information or sociological data. Both classification and regression problems can be solved using ARFF files.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ARFF) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ARFF extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ARFF file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ARFF extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ARFF extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ARFF file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ARFF file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ARFF file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ARFF file) will be extended to the maximum.
It is also good to check
- if the .ARFF file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
